To allwhom'tmay cimcem:` j f Beit known'that I,'Pnrnn A. J onANsnN, acitizen of the United States, residin `lat Omaha, in thecounty ofDouglasand tate of Nebraska, haveinvented certain new 'and usefulImprovements in (Blas-Range Lighters, of which the followingisaspeeicatlon.

This invention has reference` to automatic means for lighting gas rangeselectrically, at

`the time of turning on the as. y l The object of the inventlonjis ,torovide an inexpensive device, Yoperatedby e ectricity, which may beattached to anyordinary which will consist of few `parts and -Willberegas range, and by means of which. the burner oll the range may beautomatically lighted,

liableinoperation. f An ther object is the provision'lof devices which,when operated, will cause the `flame to be thrown a'considerable'distanca com- Earatively, from` the igniting devices, `for'ghting the burner, l"for the purpose of `pre-J venting decarbonizationof parts., f f Another object is the provisionr of devices for causingthe ignition `ilame to .be thrown upon the same horizontal plane as,`that ofthe burner; and a further Objectis the provision of .ignitiondevices Whichare `located out ofl the pathway 'of the ignitingilame,topreventdecarbonization, and the use of devlces for Vautomatically.lighting the vgas range, which .may be inexpensively replaced :whenworn or injured.

.end of gas cock-16, and vin ear with pinion Near the free endo-fp-ortion 13 ofthe disa stationary insulated mountin u 10 supply-pipe2 an charge pi e is seated insulating-ring 25, and secured t ereon isthe metal ring. 26, and upon this metal ring is mountedthe metal ost 27which extends outwardly somewhat rther than nozzle 1,7, and upon post 27is vsecured the metalffinger 28, preferably bent to form the transversecontact-blade 29; and `as thus described, contact-blade 29 has on andisdisposed adjacent the termina o 4 the dischargeipe. Contact-blade 29may be constructe of anyresilient metal and is disposed in the athtraversed vby contact-arm-. 23 during the engthwise movement of 4rod 22so that a contact of these metal parts wilh yrectlon of its arrow 90degrees, gas-cock 8 will be open, and this movement will actuate inion19 and, thereby, open valve 16 to alow gas to pass through the dischargepipe and nozzle 17; at the time of this movement arm 23 will makecontact with and will pass Y It will be noted that the metal blade 29since sparking-rod 22 will have a rearward movement. ,Any electricalTneans is employed, as battery 30, to energize wires 31 and 32, andspark-coil 33 is employed;

lwire 31 may have a metallic connection as at 34 upon thevalve-housing15 so that arm 23 of rod 22 will be energized with electricity of onesign, and wire 32 will energize blade 29 with electricity of theopposite4 sign, and at the time gas is passingl nozzle 17, a spark iscreated by arm 23 tripping upon blade 29, already explained, whichignites burner '3.

parts which coperate to produce the spark are located at a considerabledistance from burner 3 and this 'is desired so that decarbonization ofthese parts may be prevented. Cooking vessels, when placed uponthe'burner, cause lthe burning gas to flare outwardly from the burner,and in order-that the metal devices j may not be injured by the heat,they are disposed as shown, 'and an ignition iiame is thrown, inthepresent instance, from a safe distance upon the plane of the burner,and

these devices and their arrangementl will now be explained.

Nozzle 17 is provided with an oriiice 35 of less diameter than any partof the bore 36 -of the discharge pipe, and onthis account,

at the time of opening the valves as described, gas is driven from thenozzle with considerable force at the time the spark is created, so thata flame of adequate length passes from thenozzle to reach and toreliably ignite the gas of the burner. It will be noted that arm 23 andblade 29 are located near, but not at the front of orifice 32, andthereby these parts are not obtrusive to prevent a free flow of the gasat'the time the atteris forced out of the orice; also the possibility ofdecarbonization of these metal partsis minimized by reason of thislocation since they are not in the pathway of the forwardly forcedstream of flame coming from V the nozzle when the valves are open.

It will be understood by those conversant with the operation of ascocks, that gas will pass before the valve as rotated the entire 90,`degrees, and in the resent instance gas reaches burner 3 before Eandle 9has been rotated the 90 degrees mentioned. Since pinion 19 upon thedischarge pipe has a less diameter than pinion 18, its revolublemovement, when actuated, is greater than that of pinion 18; gas-cock 16,therefore, during operation, rotates more rapid and allows passage ofgas sooner than does gas-cock 8.

It will be understood,v therefore, that gas will' pass thedischarge-pipe before handle 9 has moved the full 9() degrees; duringthis movement contact-arm 23 engages blade 29 and bends the latterinwardly, since rod 22 has a lengthwise movement from the artialrotation of c linder 20; as soon, owever, as blade 29 1s tripped orreleased from arm 23 the spark is made, and at this moment gas haspassed both valves, so that the burner is lighted; when the handle hasbeen moved 90 degrees, as described, gas is freely communicated to theburner through the supply-pipe, but at this time valve 16 of the discharepipe is closed, this closure being effected y reason of the differencein diameters mentioned of pinions 18 and 19.

Pinion 18 is provided with blanks 37 and 38 upon its periphery whichoperate as stoplugs to contact with the teeth of pinion 19, to limit themovement of the gas-cocks and handle 9, and thereby prevent the turningon ofgas by use of the handle except in the manner described.

If, for any reason, blade 29 or arm 23 should become injured or worn,they may be replaced at slight expense, as they are se arate parts andare conveniently mountedp in a manner to be readily removed or replaced.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is,-

combination with a gas supply-pipe having a gascock with a pinionthereon, of a discharge pipe in communication with said supply-pipe andhaving a gas-cock with a pinion registering wi th the inion of thesupplyipe gas-cock; an insu ated metal contact-b ade 1.
